Terrestrial plants typically carry a negative electrical charge, while bees and other pollinators tend to accumulate a positive charge. A team of researchers therefore hypothesized that electrostatic attraction (mutual attraction between objects with opposite charges) might enhance pollen transmission between plants and their pollinator species. The team’s experiments showed that the maximum positive charge of wintering honeybees is sufficiently high to facilitate electrostatic pollen transfer, a finding that suggests that __________

Which choice most effectively uses data from the graph to complete the text?

A

red mason bees and houseflies, having greater maximum charges than wintering honeybees have, should not demonstrate this capacity.

B

houseflies should demonstrate the opposite tendency.

C

the minimum positive charge necessary for a pollinator to induce electrostatic attraction must be greater than 300 pC.

D

red mason bees should also demonstrate this capacity.
